"Armed struggle is a strategic option to safeguard the Palestinian cause and restore Palestinian national rights,” Hamas said in a statement issued on Saturday.
The first Intifada broke out in 1987 after four young Palestinians were killed by Israeli soldiers at a checkpoint in Gaza as well as the shooting death of a 17-year-old boy during an unarmed protest.
Intifada is an Arabic word that literally translates to "shaking off." It has been used to refer to legitimate means of resistance against oppression across the Middle East for decades. In the Arab-Israeli conflict, it means a concerted Palestinian effort to shake off Israeli occupation and gain independence.
In its statement on Saturday, Hamas said "resistance is a legitimate right guaranteed by international laws and conventions.”
It said 31 years after the eruption of the uprising, which is also known as the stone Intifada, Palestinians are still in need of unity, partnership, and the reconstruction of their national project.
The second Intifada began in 2000 and was known as the al-Aqsa Intifada. It was sparked by former Israeli prime minister Ariel Sharon’s visit to the al-Aqsa Mosque complex.
